A Query About International Post Zones From UK

Hi, My apologies for this, but my knowledge of world geography is not, and the map provided by Royal Mail is so vague that it is useless. Can anyone confirm for me please that Malaysia and Singapore are in Zone 1, and also is Hong Kong lumped in with China (Zone 2) or on it's own in zone 1?

Thanks

Singapore is Zone 2 with Australia, etc.
